Large wandering spiders in Amazonian forests

On this site we want to summarize existing published data as well as unpublished information from our own experiences with the large wandering spiders in Brazil of the family Ctenidae. These are mainly based on nocturnal excursions in the Amazon and therefore there is certainly a bias to the Amazonian fauna.

We (Thierry Gasnier, Hubert Höfer, Antonio Brescovit) started to study biology and ecology of the large wandering spiders living on the ground of Amazonian forests in 1992, within a German research programme on tropical biodiversity. Starting point of our interest in factors and traits allowing the coexistence of several abundant Ctenid species in the same habitat were observations of spatial and temporal patterns of abundances during our daily nocturnal excursions in the famous Reserva Ducke near Manaus. But first, the taxonomy of the species had to be resolved and several species were (re-)described (Höfer et al. 1994, Brescovit & Von Eickstedt 1995, Brescovit 1996, Höfer & Brescovit 2000).
